TO ALL WHOM IT MAY CONCERN:

Be it known that I, CHARLES WILLARD, of Newtown, in the county of Bucks, and State of Pennsylvania,

.have invented a new and .useful Improvement in Cultivators or Corn-Ploughs, of which the following is a full,

clear, and exact description, reference being had to the accompanying drawings, which make part of this specification, and in which- Y Figure 1 is a view in perspective of `my cultivator or plough. y

Figure is an under side view of the front teeth. or ploughs, showing my mode of attaching them to the frame; and

Figure is a view in front elevation ofthe front arched bar that unites the separate frames, and forms a socket for thc tongue.

It is the object of my invention to simplify an adjustable cultivator or corn-plough, and renderit adaptable to the culture of crops'in varying stages of their growth; and to this end my inventionlconsists, rst, in forming the frame of the cultivator or plough in t-wo separate parts, and uniting them by adjustable arched bars, the

rfront one of which forms also a socket for the reception of the tongue; second, in arranging the centre teeth or ploughs beneath thc frame, and attaching them thereto adjustably, so that they can be moved independentof the frame, to cultivate plants growing irregularly in rows without tearing them up by the roots.

I construct two rectangular frames, A and B, of suitable strengthfor a cultiva-tor. To the outside of cach I secure bearings, C and D, for bent axles E and F,f0r the wheels G and H to run upon. Over the bearings C and I` attach to the fra-me arched notched bars I and K, and to the bent axles E and F I secure hand-levers L and M, having sliding stay-rods upon them to take into the notches in the arches, and hold the frame at any desired distance from the ground for regulating the depth of ploughing,l or controlling the parallelism of the frame to the surface of the ground under culture. The rectangular frames A and B are united by arched coupling-bars N and The har N the one in front, and is formed with a rectangular box, 1P, on'its top, in which to insert the tongue Q, `while the rear end of the tongue may be secured to the top of the rear arched coupling-bar O in any secure manner. 'lfhe arched coupling-bars may be made adjustable at both ends, and thus the ploughs or cultivator teeth secured to the frame may be brought closer together when itis desirable to plough near the plants, while `the elevation of the arched eoupling-bars, and the action of the bent axles, render my cultivator capable of working over well-grown crops without injury to the standing plants. Beneath the front timbers of the frame,

I secure, in proper guides, a plate, R, to which I attach cultivator teeth or ploughs S and T, as in iig. 2, and I attach a bent rod, U, to the plate R. The rod being passed through the tongue, acts as a lever,by which the fron-t cultivator teeth or ploughs may be moved to either side, and thus, while the cultivator is in operation, the driver can shift these teeth from right to left, or vice versa, and thus cultivate as close as necessary to the growing plants without tearing them up by the roots, even when they have been planted or `come up out of line. The bar `R may be removed.when cultivating the taller growth of the plants, without affecting the operationof the cultivator teeth in the frame. i

What I claim as my invention, and desire to secure by Letters Patent, is-- i `1. The combination of the adjustable arched couplings N and O with the frames A and B, and rigid ploughs, and rigid tongue, all constructed, arranged, and operating substantially as and for the purpose set forth.

2. The combination ofthe plate R, carrying cultivator teeth or ploughs, with the frames, and with the'rod U, lwhen arranged to opera-tc substantially in the manner and for the purpose set forth.

In testimony whereof I have hereunto subscribed my name.

CHAS. WILLARD.
